Punitive US-led strikes in Syria on Saturday are justified and are an "important signal" to Iran, Syria and Lebanon’s “Hezbollah,” Israeli officials said. "The use of chemical weapons crosses a red line that humanity can no longer tolerate," Yoav Gallant, a member of Prime Minister Benjamin Netanyahus security cabinet, wrote on Twitter. "The American attack is an important signal to the axis of evil - Iran, Syria and Hezbollah," Gallant said. "Last year, President (Donald) Trump made clear that the use of chemical weapons crosses a red line. Tonight, under American leadership, the United States, France and the United Kingdom enforced that line," another Israeli official said, speaking on condition of anonymity. "Syria continues to engage in and provide a base for murderous actions, including those of Iran, that put its territory, its forces and its leadership at risk," the official said. Public radio said that Israel had been informed ahead of time of the strikes that were carried out by the United States, France and Britain in response to the alleged chemical weapons attacks in the rebel-held Damascus suburb of Douma last Saturday. The air strikes at multiple targets began around 9:00 pm Eastern Time (0100 GMT) and saw US, French and British assets firing missiles at the Bashar Assad regimes chemical production facilities. The poison gas attack in Douma killed up to 75 people including children.
